HP XA Flash EEPROM, Directions

2 System Board

Devices on the ISA Bus

Feature:	Description:

Microphone Input	• 20 dB gain preamplifier. The boost can be muted with
	software
	• 16-level programmable volume control
	• Input impedance: 600 ohms
	• Sensitivity: 30 mVpp to 200 mVpp

Stereo Out Jack	• Impedance: 32 ohms

The headphones jack and the stereo-out (audio) jack can be used interchangeably. The Windows 95 and Windows NT operating systems each have integrated drivers (Directions III).

Flash EEPROM

The PC Workstation uses 256 KB of Flash EEPROM implemented using one 8-bit ROM chip. Flash EEPROM is ROM in which the whole memory can be returned to its unprogrammed state by the application of appropriate electrical signals to its pins. It can then be reprogrammed with the latest upgrade firmware.

The System ROM contains: the LAN boot firmware, and the system BIOS (including the boot code, the ISA and PCI initialization, the Setup program and the Power-On Self-Test routines, video BIOS, plus their error messages). These are summarized in Chapters 4 and 5.

The Flash EEPROMs on the HP Kayak XA PC Workstation implement a bootblock feature which allows recovery from a failed attempt at updating the System BIOS. The bootblock contains the minimum system BIOS information necessary to reprogram the Flash EEPROM.
